PDSN Service Configuration for L2TP Support
PDSN service configuration is required for compulsory tunneling and optional for attribute-based tunneling.
For attribute-based tunneling, a configuration error could occur such that upon successful authentication, the system
determines that the subscriber session requires L2TP but can not determine the name of the context in which the
appropriate LAC service is configured from the attributes supplied. As a precautionary, a parameter has been added to
the PDSN service configuration options that will dictate the name of the context to use. It is strongly recommended that
this parameter be configured.
